To do this process easily and quickly, use a special device called an OBD-II scanner which will allow you to connect these two systems without any hassle.

Step 2: Keyless Entry:

Finally, after remote pairing has been completed successfully comes programming the key itself – also known as ‘keyless entry’.

You must insert your new (or old) key into your car’s ignition slot, then press the unlock button twice on the dashboard. The car should respond by recognizing your key and allowing access accordingly.
